Catalyst 3750 Switch Hardware Installation Guide
78-15136-02
Power Connectors
The switch is powered through the internal power supply. You can also connect
the Cisco RPS 300 or the Cisco RPS 675 to provide backup power if the switch
internal power supply should fail.
Note
The Catalyst
3750 switch and the Cisco
RPS 300 or RPS 675 should be connected
to the same AC power source.
Internal Power Supply Connector
The internal power supply is an autoranging unit that supports input voltages
between 100 and 240 VAC. Use the supplied AC power cord to connect the AC
power connector to an AC power outlet.
Cisco RPS Connector
Specific Cisco RPS modes support specific Catalyst 3750 switches:
•
Cisco RPS 300 (model PWR300-AC-RPS-N1) supports the
Catalyst 3750-24TS, 3750G-24T, 3750G-12S, and 3750-48TS switches.
•
Cisco RPS 675 (model PWR675-AC-RPS-N1=) supports the Catalyst 3750
family of switches.
Cisco RPS 300
The Cisco RPS 300 has two output levels:
–
48V and 12V with a total maximum
output power of 300W. Use the supplied RPS connector cable to connect the RPS
to the switch.
Note
The Cisco RPS 300 does not support the Catalyst 3750G-24TS switches.
Warning
Attach only the Cisco RPS (model PWR300-AC-RPS-N1) to the RPS receptacle.
